The short GRB070707 afterglow and its very faint host galaxy
S. Piranomonte, P. D'Avanzo, S. Covino +18
We present the results from an ESO/VLT campaign aimed at studying the afterglow properties of the short/hard gamma ray burst GRB 070707. Observations were carried out at ten differ…
The Simbol-X view of the unresolved X-ray background
A. Comastri, R. Gilli, F. Fiore +3
We will briefly discuss the importance of sensitive X-ray observations above 10 keV for a better understanding of the physical mechanisms associated to the Supermassive Black Hole…
Heavily obscured AGN with BeppoSAX, INTEGRAL, SWIFT, XMM and Chandra: prospects for Simbol-X
R. Della Ceca, P. Severgnini, A. Caccianiga +6
According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton Thick AGN should represent ~50% of the total absorbed AGN population. However, despit…
The evolution of AGN in the Hard X-rays from HELLAS
F. La Franca, F. Fiore, C. Vignali +3
We present optical spectroscopic identification of sources identified in the BeppoSAX MECS fields of the High Energy LLarge Area Survey (HELLAS). In total 62 sources from a sample…
